RAILWAY-CAR.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed December 7. 1906. Serial No. 346,820-

' To all whom it may concern:

Be it known that we, GEORGE Tnoaras MARTIN and WILLIAM HENRY DART, bothof Smiths Falls, in the county of Lanark, Province of Ontario Canada,have invented certain new and useful improvements in Railway-Cars, ofwhich the following is a specification.

Our invention relates to improvements in railway cars and the objects ofour invention are to provide an improved simple strong and compact carwhich will not telescope or override in the event; of a collision or anyother sudden change in velocity and thus save both life and property.

- This object is accomplished by forming the cars so that they will abutalong planes inclined at an acute angle to the line of movement wherebyany sudden impact instead of being transmitted is diverted laterally atthe end of each car causing the cars in place oi telescoping to swinglaterally on the track and remain intact.

An embodiment of the invention is illustrated in the accompanyingspecifications and drawings.

Figure l is a side elevation between two cars made in accordance withour invention and having the vestibules thereon. Fig. 2 is a horizontalsectional view through the same. Fig. 3 is a plan view of the underframe of the cars. Fig. 4 is a partially diagrammatic view illustratingthe action of the cars in case of accident.

In the drawings like letters of reference indicate corres iionding partsin each figure.

Referring to Figs. 1, 2 and 3 A and B are two cars of any suitable ordesirable construction provided as usual with vestibules a and b at eachend thereof.

C and D are the steel underframe of the car of well known construction.

in accordance with our invention two or more of the main beams 1: and dof each frame are extended beneath the platform and joined at their endsby face plates 0 inclined at an acute angle to the direction of movementof the car that shown being substantially at fortyfive degrees. Theusual type of coupling E is provided beneath the frame. As shown the twoface plates 6 of adjacent cars will be parallel to each other. At theextremities of each of the platforms substantially square-shaped lateralextensions 7: and l are provided. which will support, when complete, theusual space in the vestibule to accommodate the passengers. Thevestibules a and b on the cars will also be con structed with adjacentinclined face plates] and g with the opening for the passage way betweenthe face plates f and g, but the vestibules at their outsides. m and n,will extend a distance in a direction at right angles to the line ofmovement of the car, but their center portion 0 will be inclined to theline of said direction and parallel with the beveled edge on theplatform beneath. The portions n and 0 at right angles enable squarespaces 1) and q to be provided in the vestibule on top of the extensionsI: and Z. Otherwise however, their construction will be the same as thatgenerally adapted and they will be provided with the usual exit doors hand steps i. The engine of the train may also have its end inclined.

Referring to Fig. 4 which illustrates the operation of the device 3. 4and 5 represent a train of cars travcl ing in the direction indicated bythe arrow. Should the cars meet at the point 6 an obstruction ofsufficient power to suddenly reduce the velocity of the train oraltogether stop it then the impact caused by the sudden stopping andreduction of velocity in the train produces a repulsive force suiiicientunder ordinary conditions to crush the cars together, the platforms ofeach car being lifted somewhat from the track and placed over theplatform of the preceding car tearing the non-resistant material of theupper part of the car and destroying both life and property. If howeverthe cars are constructed in accordance with our invention with inclinedends then the reactive force in place of acting in this manner to causethe cars to crash together will be diverted laterally as it passes fromcar to car causing the end of the ar to slide along the line of leastresistance which will cause the cars to leave the track and come to restin a line more or less inclined at right angles to the track; The fulland dotted lines in the drawings indicate two different positions whichmight be assumed by the cars in the event of stoppage. It will thus beseen that any force which would cause the cars to crush together isdiverted and acts to swing the cars on the tracks into a position ofsafety.

It is evident that the invention might be employed with any form of carconstruction, the essential feature being that the adjacent ends of thecars are inclined at an acute angle to the direction of movement of thecars.

What we claim as our invention is;

In an anti-telescoping car. the combination with two cars of a pluralityof beams outwardly protruding); from the center of the same, face-platesconnecting the ends of the beams disposed at an angle to the directionof movement of the car. a platlform projecting laterally from theextremities of the longest beams of each car, platforms adapted toprovide the free space in the vestibules for convenience in 1) age, andsuitable vestibules disposed above the said platforms, the faces of thesaid vestibules having their center portions disposed at an acute angleto the direction of movement of the car and their outer portion at rightangles thereto.
